Application led November 4, 1914. Serial No. 870,315.

To all whom t may concern Be it known that l, RICHARD T. NEWTON, a citizen of the United States, and resident of Nutley, in the county o t Essex and State of New Jersey, have invented certain new and useful lmprovements in Vehicles, of which the following is a specication.

IThis invention relates to springed vehicles provided with shock neutralizers and has inview the production of a vehicle that is capable of passing over rough roads without inconvenience to an occupant or injury to its working parts. Other objects will appear from the Specification and claims and the drawing in which- Figure 1 is a vertical section showing the ends ci two leaf springs to which is attached a shock neutralizer.

Fig. 2 is a similar section showing a modified form of attaching the shock neutralizer.

F ig. 3 is a similar section in which the Shock neutralizer is shown as occupying a substantially horizontal position.-

Fig. 4 is a bottom view of the casing in Fig. 1.

Fig. 5 is a section showing two leaiLl springs and a shock neutralizer substantially parallel with one of the leaf springs.4

Fig. 6 is an elevation of the closed end ot the casing in Fig. 5, and

Fig. 7 is a top view of the shock neutralizer shown in Fig. 5.

Referring to the drawings, there is shown the ends of two leaf springs 10 and 117 a casing of a shock neutralizer 12 being attached to the spring 11 at the top of its upper part 13 by means of the hinge or bolt 14. inside the casing 12 are located the coiled springs 29 and 30 and between them is shown the partition 15 p-ivotally attached by means of the hinge or bolt 15 to the rod 16 also attached to a lever 17 by means ot the hinge or bolt 18. @ne end ci the lever 17 is pivotally attached to the spring 10 by means ot the hinge or bolt 19, the other end being pivotally attached to the linh 21 by means of the hinge or bolt 20, the link 21 being attached to the casing 12 on the bracket 22 by means ot the hinge or bolt 23. By means of this construction the lever 19 passes across the upper part ot the shock neutralizer, a construction which results in great compactness and in the shortening of the lever required. To the bracket 22v is also attached the link 24 connected with the fastening element 25. It will thus appear that the casing 12 is flexibly connected with the spring 11 at two oints. Above the coiled spring 29 is located) a ring or a plate 26 with an opening for the rod 16. At the bottom of the `casing is a. screw cap 27 by means oi which the tension of the coiled springs is regulated. The screw cap 27 is held securely in place by the conical screw 28, passing through a slot, 27, in the cap 27.

ln the modiiied construction shown in Fig. 3 the casing 12 has a horizontal position. 1n this case the spring l() is attached at 35 to the bell crank lever 32 having its i'ulcrum at 33, the other end of the lever being pivotally connected at 34 with the rod 16. This con struction is of importance because thereby the flat spring acts directly on the lever 32 avoiding lost motion and dead centers, and the action is instantaneous. The tact that the fulcrum is attached to the casing simpliles the construction and makes it more comthe fastening element 37 hrmly attached to the spring 11:

Ign the modified construction shown in Fig. 5 the casing 12 of the shock neutraliser is at one end iieXibly attached to the leaf spring 11 by means of the link 38, hinged or pivoted at 39 and 40, and at the other end it is dexibly attachedrat 36 by means of the link 3? connected at 41 with the plate 42 irmly held on the leal2 spring 11 by means oi' the clamps, 43, 43.

@n accountof the flexible attachment the casing of the shock neutralizer at each point all strains are avoided, so that the mechanism operates freely. rlhis torni ot attachment also placing the shock: eliminator below the leaf springs has the advantage that the shock neutralizers are not in the way in the operation ot the vehicle', to which they are attached, while at the saine time they are protected from mechanical injury.

The advantages of the lever used are first that the movement of the elastic element in the shock eliminator may be varied at will by a proper adjustment ot the arms of the lever, that a strong spring may be used and may be made suihciently sensitive by making the arm of the lever not connected with the casing, of sufficient length. 1t also facilitates the construction by making it possible to place the casing bach ot and some distance from the springs. It also allows great movement 'for the leaf springs With small movement ot the coiled springs which is very desirable, the load of the springs being maintained more uniform and the springs therefor more elastic.

What l claim as nen7 is:

l. For use with a vehicle having a body part and a supporting spring therefor associated with the running gear, said body part and spring being separated at their adjacent ends, a seit-contained shock neutralizer attachmentadapted to be interposed between said ends when the latter are separated, and means or securing independent elements ot the neutraliser to said ends respectively to operate the neutralizer on the relative vertical displacement ot said ends, one of said elements comprising a casing, a neutralizer spring Within the same, and the other of said elements comprising a lever pivoted to said casing and operatively associated With the neutraliser spring, said casing having means for removably attaching` it beneath the supporting spring adjacent the end of the latter.

2. For use with a vehicle having a body art and a su) ortinos rino` therefor associated With the running gear, said body part and `spring being separated and apertured at their adjacent ends, a seit-contained shoclrneutralizer attachment comprising a casing jointed to one ot' said ends at its aperture'd point, lever jointed to the other of said ends at its apertured point and also to the casing, a neutralizer spring housed Within said casing and an operative connection between said lever and neutralizer spring to operate the latter on the relative vertical displacement et said ends, said casing having means 'for removably attaching it beneath the supporting spring adjacent the Aend oit the latter.

3.
